<p>According to the invention, an iterative searching operation is carried out to find the optimum advance angle value opt by periodically adding an advance angle DELTA) to the instantaneous advance angle o and by detecting the instantaneous speeds N1t and N2t which correspond to the advance angles o o + DELTA), and the direction of the variation DELTAN of the speed of the motor is determined so as to correct the advance angle o so that the variation DELTAN is as small as possible, or even zero, so that the advance angle o is maintained close to its optimum value opt. At transient operating conditions, a "floating mapping" is superposed while taking into account an advance curve as a function of the motor speed. The method may be used for the regulation of the ignition advance of motor vehicles. </p> |
